450 ohm Ladder Line Holder/Insulator

A friend of mine (WB2GMY) need something to hold/insulate his ladder line to his house so i helped him create this. we used a number of these every few feet of line. We used on long deck screw in the center which allowed us to keep it further away with longer screws. and 2 smaller screws to hold the lid onto the base. (will update post with actual screws used)
